Moody’s Cuts Botswana Rating as Diamonds Slump
Africa’s model diamond economy keeps its investment grade, but the cushion is thinner after a second cut in under a year.
Moody’s Ratings lowered the Botswana credit rating to Baa2 from Baa1 on Friday 25 September 2026. The agency, one of the three big global raters, blamed weaker diamond revenue and worsening public finances.
Botswana is a small, stable democracy north of South Africa, best known abroad for diamonds and safaris. For decades it used diamond income to build roads, schools and savings, which made it a rare African investment-grade borrower.
Key Facts
- The country. Botswana is a landlocked southern African democracy of about 2.6 million people. Its economy, about US$20 billion in 2025 (World Bank), is smaller than Iceland’s. It is a leading diamond producer by value.
- Why it matters. Diamonds supply about one third of government revenue and three quarters of foreign-exchange earnings. Botswana has long been one of Africa’s best-run economies, with investment-grade credit ratings.
- Why now. A long slump in natural diamond demand, driven by economic uncertainty and cheaper lab-grown stones, has drained state revenue and savings.
- What happened. Moody’s Ratings cut Botswana’s long-term rating to Baa2 from Baa1 on Friday 25 September 2026, its second cut in under a year. The outlook moved to stable.
- The numbers. Moody’s expects government debt to reach 41% of gross domestic product (GDP) in fiscal 2027, up from 31% in fiscal 2025.
- What it means for you. Baa2 is still investment grade, two notches above junk. Bond investors face thinner protection; travellers and safari visitors see no direct change.
- Still open. Whether Botswana borrows to buy a bigger stake in De Beers, the diamond miner. Moody’s says a debt-financed deal could trigger another cut.
Why Moody’s cut the rating
Moody’s named three pressures on the budget. Diamond revenue is lower, and newly introduced taxes have raised less than hoped.
The third is the Southern African Customs Union (SACU), a regional pool that shares tariff income among five neighbours. Its payments to Botswana came in below expectations.
Diamonds typically provide about one third of state revenue and three quarters of foreign-exchange earnings, Reuters reported. A long slump in the global diamond market has therefore reached the budget directly.
Demand for natural stones has weakened as buyers turn to laboratory-grown diamonds, which look the same and cost far less. Economic uncertainty in the big jewellery markets has added to the pressure.
What the numbers show
Moody’s expects gross government debt to rise to 41% of GDP in fiscal 2027, from 31% in fiscal 2025. Botswana’s fiscal year runs from April to March.
The agency also expects interest payments to absorb about 5.9% of government revenue by 2027. That is still modest by African standards, but the trend is upward.
Moody’s says Botswana’s financial buffers have been substantially eroded. Its October 2025 downgrade noted that the government’s investment account had been almost entirely drawn down to cover deficits.
A better budget forecast, but a lower rating
The cut came three days after the finance minister, Ndaba Gaolathe, gave a brighter budget update on 22 September. He now expects a deficit of 9.26 billion pula (about US$654 million) for the year to March 2027.
That equals 3.1% of GDP, against an earlier forecast of 26.35 billion pula (about US$1.86 billion), or 8.9% of GDP. Conversions use 14.17 pula per US dollar, the market close on 2 October.
Revenue was revised up by 8.1 billion pula (about US$572 million). A larger transfer from the Bank of Botswana, the central bank, helped.
Moody’s judged the gain insufficient to reverse the longer-term deterioration.
Ecofin Agency, a business news service, noted that the improvement rests largely on one-off measures and spending cuts. It said new, lasting sources of revenue are still missing.
S&P Global, another major rater, affirmed Botswana at BBB-, its lowest investment-grade step, on 11 September. Both agencies now place the country close to the junk line.
Why the outlook is now stable
Moody’s moved the outlook on the Botswana credit rating to stable from negative. It does not expect another change soon.
It cited a stronger fiscal response and the chance that a diamond recovery slows the build-up of debt.
The agency also pointed to Botswana’s strong institutions, deep domestic capital markets and still substantial foreign-exchange reserves. The Bank of Botswana put reserves at about US$4.16 billion in June 2026.
What it means for you
For investors, the Botswana credit rating remains investment grade, so most funds can still hold its debt. A further cut, however, would bring the country one step from junk and raise borrowing costs.
For residents and expatriates, the main risk is pressure on public spending and services if diamond income stays weak. Prices are already rising fast: inflation was 9.3% in August, above the central bank’s 3–6% target.
For travellers, nothing changes directly. Safari lodges, flights and visas do not depend on the rating, though a weaker budget can slow spending on roads and airports.
What could tip it the other way
Moody’s warned it could cut again if Botswana materially increases its investment in De Beers through debt-financed deals. Botswana already co-owns the diamond miner, and Anglo American aims to sell its majority stake in the fourth quarter.
A sustained recovery in diamond sales would help most. Debswana, the joint venture of the government and De Beers, mines nearly all of the country’s diamonds.
The central bank holds its main interest rate at 5.50%. Its Monetary Policy Committee (MPC), which sets that rate, meets next on Thursday 29 October and Thursday 3 December 2026.
What is not known
The final terms of any De Beers deal are not public, and neither is whether Botswana would use debt to fund it. How quickly diamond demand recovers is also uncertain.

Is Botswana still investment grade?
Yes. Baa2 is investment grade and sits two notches above junk. S&P Global rates Botswana BBB-, its lowest investment-grade step.
Why do diamonds matter so much to Botswana?
Diamonds typically provide about one third of government revenue and three quarters of foreign-exchange earnings. A weak diamond market hits the budget directly.
